6. First Use and Conditioning

To optimize the performance and longevity of your new Lithium-ion battery, follow these initial conditioning steps:

1. Initial Discharge: After installation, use the laptop on battery power until the battery level reaches approximately 10% (do not let it discharge to 0%).
2. Full Charge: Connect the AC adapter and charge the battery to 95-100% without interruption.
3. Repeat Cycle: Repeat the discharge to 10% and full charge cycle 3-4 times. This process helps to calibrate the battery and 'wake up' the new cells.

7. Battery Care and Maintenance

Proper care extends battery life and ensures consistent performance:

• Avoid Prolonged Charging: Do not leave the laptop connected to the AC adapter for extended periods after the battery is fully charged, as this can degrade battery health over time.
• Storage: If storing the battery for a long time (e.g., more than a month), charge it to at least 80% before storage. Store in a cool, dry place.
• Temperature: Operate your laptop within recommended temperature ranges. Extreme heat or cold can negatively impact battery performance and lifespan.
• Power Settings: Adjust your laptop's power plan settings to 'Power Saver' and reduce processor state to 20% when on battery to maximize runtime.
• Cleanliness: Keep your laptop clean. Dust can accumulate in vents, leading to overheating which affects battery performance.
• Disable Unused Features: Turn off Wi-Fi, Bluetooth, and other unnecessary features when not in use to conserve battery power.
